Radiative capture reactions in lattice effective field theory

Understand

We outline a general method for computing nuclear capture reactions on the lattice.

• The method consists of two major parts.
• In this study we detail the second part which consists of calculating an effective two-body capture reaction on the lattice at finite volume.
• We solve this problem by calculating the two-point Green's function using an infrared regulator and the capture amplitude to a two-body bound state.
